The DS3 is fine, but they need to change the R2 and L2 buttons. Here is my list of must haves on the PS4.

1. Optional HDD replacement just like the PS3.

2. Enough RAM to last 7 years

3. A dashboard that exceeds the Xbox.

4. Cross game chat

5. 4+ USB ports

6. All of my store purchases must be transferable to the PS4.

Hell yes, DS4 is must Sony need to that classic design & just had newer tech to it
and have 30+ PSN games that are locked to my PS3, if I can't transfer or access them I'm gonna feel like I wasted money, that I hate DLC.

All i want is my 3 console requirements met. 1 - At least 5 games announced within the first 2 years i want to play. 2 - At least somewhat traditional controller packed in with the console. 3 - Free online service with optional pay service like Sony has now with PS3. Only thing stopping me from buying a Wii U is #1 there isn't even one game i want for it yet. Besides that stuff though i would really like SSD and Oculus Rift support but i doubt it.
